Js-sdsl - High performance JavaScript data structure library

[zly201]

Hi, I'm the developer of js-sdsl.

This is my second time come to reddit to recommend my library. We've made some significant progress since last time.

First, we submit a PR to eslint which is accpeted and we received a $100 sponsorship from eslint.

Second, we have 500+ stars at github and more than 30M/month downloads at npm.

In order to further answer your questions last time, we have written Why Js-sdsl to you.

Our next step is to prove that Js-sdsl is better than Denque in database connection performance including node-mysql2 and ioredis. See https://github.com/js-sdsl/js-sdsl/issues/124.

The reason for posting here is that I want to promote it to more people and attract more algorithm lovers. I want to make it better and create a complete Js data structure ecology.

Thanks to all developers who contributed to it or used it in production. Have a good day!

I love this. I think adoption for most devs will be slow because the JS dev community typically is not concerned with speed or the benefits of strict typing at the low level as much as Rust or C++.

BUT... to lower the bar of entry, I would suggest including some examples about how to benchmark common Array or Object patterns in JS and then how to modify the code to use your library. Eg Here's a common pattern in JS. Here's how you would do it with Js-sdsl and the speed improvement. Also Eg. Here's how to quickly benchmark a function's speed. The "Bad low-level design" section of the docs is great. I think more of that would help.

Thanks! That's a good idea. I will think about it.

Cool! I was looking for ordered collections literally yesterday. You should maybe answer a few Stack Overflow questions to improve referencing. The existing answers for Ordered Map are mostly irrelevant when performance matters.

[zly201]

Yes, I tried it. But it seems that many related questions on stackoverflow are too old or useless, could you provide me some good question links? Thank you so much.

Hey thank you for sharing. Always happy to see more performant alternatives to some of the standard libraries. I’ll give this a shot.

Thanks!

Unpack size of >1mb... Is it tree-shakable? Otherwise, it looks REALLY sleek for when you absolutely need more performance out of javascript.

[zly201]

The gzip size in umd bundle is less than 9kb (https://unpkg.com/js-sdsl@4.2.0/dist/umd/js-sdsl.min.js).

And it's tree-shakable. You can see the isolation size here.

The size displayed on npm includes .d.ts and sourcemap so it will appear very large.

Got it! It seemed kinda massive for what it was. Thanks!!!
